Amazon is currently taking 35% off when you buy 10,000 Amazon Coins. That brings the normally $100 worth of coins down to just $65. This is one of the best deals on Amazon Coins that I’ve seen in a while. Amazon Coins can be used in the Amazon Appstore to buy apps or games, and can also be used within apps to make in-app purchases. If you spend any money at all on apps, it’s silly not to first purchase Amazon Coins because they give you a much bigger bang for your buck. This promotion ends on December 29th.
